Next Generation of Biogas
As we know, the formation of biogas is a natural phenomenon that naturally occurs in wetland, manure stack, human and animal intestines. And for centuries, humans have harvested the power of bacteriological digestion, by recovering naturally formed biogases to use them as cooking gas, heating gas or engine fuel.
Let's check next generation of biogas:
1. Bio-Hydrogen (Biohydrogen) (BioH 2)
Today, ground breaking biotechnology discoveries have brought new hope for the hydrogen (H 2) economy. Bacteriological digestion/fermentation of organic waste holds the promise of biological production of H 2.
The clear advantage of bio-hydrogen over biogas is that BioH 2 produces virtually no Greenhouse Gases.
2. Fuel Cell
A fuel cell is a system that directly converts a gaseous chemical reaction into electricity. In the typical fuel cell, pure hydrogen (H 2) reacts with oxygen (O 2) from the air to create water (H 2O), heat and electricity.
Before the advent of fuel cell technology, internal combustion engine generators were the sole alternative for conversion of bio-methane into heat and electricity with a typical 25 to 40 % efficiency range.
Today, several companies offer direct methane fuel cell systems for silent production of green energy (renewable energy) from bio-methane.
